[32.07] Spatial Heterodyne Spectroscopy as a tool for dynamical studies of angularly extended faint emissions in the solar system.

F. Roesler, J. Corliss (University of Wisconsin-Madison)

Ultraviolet astronomy is an important tool for the study of the interplanetary medium and diffuse, angularly extended emissions in planetary/comet atmospheres and their near space environments. We describe a new technique for high étendue observations of emission lines at R >105 with an all-reflective spatial heterodyne spectrometer and polarmetric sampling of these lines with an ultraviolet optimized waveplate-Brewster mirror combination. The resulting system is themo-mechanically stable, has light collecting power substantially greater than HST for extended emissions, despite having a volume of several x 10-3 m3. This makes the SHS polarimeter ideal for spacecraft and remote sensing applications. The SHS technique is described along with several sample applications for which it is ideally suited.
